Abstract
La presente se refiere a un proceso para el tratamiento de ceniza arrastrada que se acumula en el electro-filtro de la caldera de recuperacion de sosa enla fabricacion de celulosa al sulfato, la ceniza contiene, fundamentalmente, sulfato de Na,cloru ro de Na, carbonato de Na y sulfato de K, a fin de producirmateriales industriales, en dicho proceso la ceniza arrastrada se disuelve en agua, el carbonato que se encuentra presente en ella se descompone con ácidoclorhídrico a cloruro de Na,se agreg a una sustancia química de precipitacion de sulfato en forma de cloruro, el precipitado de sulfato que se obtiene sesepara de la solucion, y se recupera la solucion con contenido de cloruro.
